To all whom t may concern.

Be it known that we, JOHN ARTHUR Krinsnr and ALFRED SHEDLOACK, citizens of the United States, residing, respectively, at Brooklyn, county of Kings, State of New York, and Cannondale, Fairfield county, State of Connecticut, have jointly invented new and useful Improvements in Signaling Apparatus, of which the following is a speci- Jfcation.' v i This invention relates to signaling systems which involve the mechanical transmission of orders or messages; it is based, in general principles, on the a paratus shown and described in the pending application for Letters Patent of John'Arthur Keesey, filed December 5, 1916, under Serial Number 135,163. y

The object of this invention is to simplify the sound producing mechanism, to amplify the visual signals or orders, whereby the person sending the orders will have closer and more erfect control over the resultant effects ue to the execution of his orders, and to generally improve the efficiency of mechanical signaling apparatus.

The accompanying drawings illustrate em:

bodiments of the general features of our invention, in which:

The face or front of a message receiving apparatus adapted for marine use is shown at Fig. 1. llts dial 11, is inscribed with two sets of orders, the one set 12, being instructions for starting and stoppingl and main divisions of speed, ahead and astern, and the other set 13, indicates instructions for a greater or less number ot revolutions between the main s eeds at which the engines are to be run. his apparatus is provided with four indexes or pointers, those marked 14, and 15, are actuated by the order sending apparatus to indicate'the main and revolution speeds respectively, and those marked 16, and 17, are adapted to be set by the engineer or order receiving attendant, over the order or orders received to transmit to the sending apparatus, by setting corresponding indicating pointers, information that the order or orders is or are executed or being `bearings for the main devices of the machine. rllhe plates 25, and 26, have opposed flanges, the upper parts of which contact,

and they are secured together' by screwsV 29, the rest of the {langes are spaced apart to aHord a slot opening for one of the operating handles.

The order indicating dial is attached to the top plate 28; or the orders may be marked on the plate or otherwise applied thereto.

Between the bottom and center plates 25, and 26, are four chain carrying pulleys 30, 31, 32, and 33, the lower one 30, being rigidl secured to or formed integral with a sha t 34, the lower end of which has a bearing in the plate 25, 'the next one 31, is fitted torotate on the shaft 34, the next or third pulley 32, has a long sleeve 35 adapted to rotate on the shaft 34, and extends up through and has a bearing in the top plate 28, and the upper or fourth pulley 33, is on a sleeve 3,6, which extends through and has a bearing in' the center plate 26.

Chains 37, 38, 39, and 40, are respectively secured to and extend in both directions around the pulleys 30, 31, 32, and 33, and these chains are guided by pulleys 41, and 42, as they pass through an opening between and at the upper parts of the plates 25, 26.

Cn the sleeve 36, of the pulley 33, just above the center plate 26, is secured, by a screw or other suitable means, a disk 43, provided with teeth 44, and in `close proximity to and above this disk is a disk 45, having teeth 46,'and fastened to the sleeve 35,'of the pulley 32.

' 35, of the The main signal indicating pointer 14, 'is rigidly secured to the outer end of the sleeve ulley 32, and the pointer 15, indicating the revolutions is attached to an arm 47, securedto and extending from one side of the disk 43.

The return answer of the main speed signals is accomplished by the movement of the pulley 31, brought about by the manipulation of the handle 48, by the order receiving attendant; this handle is attached to or forms part of an arm 49, which is fastened to the pulley 31, and extends, through the slot opening between the ianges of the plates 25, 26. The pointer 16, is secured to the upper end of the arm 49. The rotation of the pulley 31, by its attached chain 38, causes the pointer ofthe sending apparatus to be set over the speed indication, corresponding to the speed order indicated on the dial 11, of the receiving apparatus over which the pointer 16, is set.

0n the upper end of the shaft 34, is fastened an arm 50, provided with a handle 51, and which also carries thepointer 17. By manipulation of this handle the pointer 17, is set over the revolution signal received and through the medium of the pulley 30, and its attached chain 37, causes the return answer ointer to be set over the corre'- sponding or er on the dial of the sending apparatus.

Aural signals are twice given as the main order pointer 14, moves from one division of the set of orders 12, to another, thereby insuring that one such signal will be sounded should loss motion, from wear or other causes, occur in the operative connections between the two apparatus. By this invention only one set of teeth are used to actuate the two gong sounding devices, as teeth 46, on the periphery of the disk 45.

Mounted to rock on posts 74 projecting from the frame plate 26, adjacent the disk are spring actuated levers 75, and 7 6, the

upper ends of which carry the hammers 7 7 arranged, when released to strike a gong 78, This gong is by its central part secured to the under side of the top plate 28, of the frame.

It is a prerequisite in this style of signaling apparatus that the hammers be alternately actuated by the teeth 46, inboth d1- rections of rotation of the disk 45. To this end a lever controller in the form of a double acting pawl 7 9, is pivotally connected to each of the short arms 80, of the levers 75, 76. A suitable connection consists in providing the pawls with wings 81,- adapted to embrace the sides of the levers and a pin or bolt 82, passing through the wings and` levers, as shown at Fig. 4.

The pawls have opposed stop edges 83, 84, which contact with the edges of the arms 80, to positively impart motion to the levers as the teeth 46, act on, by sweeping over, the o erating projections of the pawls. The e ges 83, act as stops when the teeth have a left hand motion and the' edges 84 act as stops when the teeth move in the opposite direction; the arrangement and locations of the pawls being such that when one of them is actuated the other one will be between two adjacent teeth of the disk 45, and also that as soon as the points of a tooth and the coacting projection of a pawl clear one another, the pawl, by reason of its free swinging connection with the lever, will as the lever is thrown forward b its spring, swing clear of the tooth,thus ositively insuring freedom of action o the lever; furthermore neither pawl will interfere lwith the free action of the other, and as soon as a tooth has released a pawl anothe1 tooth is in position to act on another paw y A single spring 85, actuates the two hainmer levers 75, 76, by forming 'a resilient connection between the arms 86, of the levers,

normally holding the levers against the stop pins 87, 87. The levers will be thrown violently against said pins as their pawls are eleased from the teeth of the disks 43, and

The requirements of some installations of the apparatus call for the employment of two sets of signal orders, as shown and described; in other cases where one set of signals is sufficient it will be understood that the operative mechanism of the second set of signals may be readily omitted without detriment to the operativeness of or principles involved in the invention.

When the two sets of signals are used the same gong striking mechanism is common to the two sets of orders, and, as the disks 43, 45, are coaxial their teeth will act on the pawls 79, in the same manner. Each disk will separately perform its function without interference with or by the other.

The teeth 44, of the disk 43, may be spaced apart, or have the same pitch, as' the teeth 46, of the disk 45; but in the drawin they are shown with a smaller pitch. T is arrangement provides for a greater number of divisions in a given segment of 'the dials. The sizes and arrangement of the signal divisions on the dials is immaterial as regards the practice of this invention, the essential feature being that two or more hammers are actuated by a single set of teeth, and that when two sets of signals are used, each having its individual toothed disk, both sets of' teeth will act on the same ong strikin mechanism independently of t e other; an that when the two disks are used their teeth will be so spaced and arranged as not to interfere with the proper action of the two sets of teeth on the pawls of the hammer levers.

masacre In the modication lEig.. 7, the two hammer levers 75, 76, have a rocking bearing on a single stud 88, the short arm of the upper one being above the long arm of the lower one and the short arm of the lower one beneath the long arm of the upper one. These short arms carry the double acting controlling pawls 79, in the manner before described.

lln the modification Fig. 8, the short arms 'of the levers are actuated by all of the teeth of the disk through the medium of controllers in the form of double tappets 89, and 90, held on stud bearings 92, and adapted to set the levers in active positions as the teeth of the disks act on the points 91, of the tappets. The operations of the toothed disks rocking the hammer levers of these two modications are in all essential respects similar to that of the gong striking mechanism previously described, in that all of the teeth of each disk actuate both volf the associated hammer levers.
